Job description
Take ownership of how data, paid activation and marketing technology drive growth, conversion and commercial impact.
LanguageWire is scaling its digital marketing performance across markets, channels and customer segments.
We operate a modern marketing ecosystem built on a global website (Umbraco), a clean server-side tracking setup, and HubSpot as our central Marketing Hub. The foundation is in place. The next step is to optimise performance, improve efficiency, and scale what works.
As Data & MarTech Lead, you will own the performance framework behind our digital marketing efforts -ensuring that paid activation, SEO, GEO, website experience, CRM and data work together to drive measurable business impact.
This role is about turning traffic into demand, demand into pipeline, and insight into action.
The role you’ll play
As Data & MarTech Lead, you own the performance backbone of our digital marketing.
You define how success is measured, where optimisation effort is focused, and how data, technology, internal teams and external partners come together to drive growth. You ensure that paid media, SEO, GEO, website experience and CRM are aligned around clear priorities and measurable outcomes.
1. Marketing Performance Strategy & Optimisation
Define performance strategy, targets and optimisation priorities across:
- Paid activation
Google Ads (Search) and LinkedIn Ads (incl. retargeting and ABM), in close collaboration with channel owners and agency partners.
- SEO and GEO visibility
Ensuring search and AI-driven discovery efforts are aligned with authority, structure, intent and commercial priorities.
- Website conversion and user journeys
From first visit to qualified lead.
Own and continuously improve:
cost per qualified lead,
session-to-lead conversion,
pipeline contribution and efficiency.
Set the commercial and conversion optimisation framework for the website, guiding experimentation, UX improvements and prioritisation.
2. Paid Media & Agency Leadership
Own the performance framework for paid activation, including:
targeting and segmentation logic,
conversion measurement and attribution,
budget allocation and testing priorities.
Lead external agency partners for paid media:
briefing and goal-setting,
execution standards and QA,
weekly optimisation rhythm and learning agenda,
performance reporting tied to CRM and pipeline outcomes.
Ensure strong alignment between paid traffic, landing pages, tracking and lead-quality feedback from Sales.
3. Data, Tracking & Performance Insights
Own the measurement architecture (GA4, server-side tracking, GTM) and data governance.
Ensure reliable, consistent performance data across the full funnel.
Lead the development of dashboards and insight frameworks for:
leadership and board reporting,
performance optimisation,
day-to-day decision-making.
Translate data into clear recommendations, trade-offs and priorities — even when signals are imperfect.
4. CRM, Automation & Lifecycle Enablement
Own the performance framework, data model and commercial alignment of HubSpot.
Ensure clean lead flows, lifecycle stages, scoring and alignment with Sales.
Enable scalable automation and nurture programs that support conversion, activation and retention.
Safeguard data quality, permissions and compliance.
5. Strategic Partner & Orchestrator
Act as the connective tissue between channels, platforms, internal teams and external partners.
Challenge initiatives that are not measurable, scalable or impactful.
Own the MarTech roadmap with a clear impact-vs-effort mindset.
Evaluate new tools pragmatically — value before novelty.
In one year, you’ll know you were successful if…
Paid performance efficiency improves measurably across Google Ads and LinkedIn.
SEO and GEO visibility strengthen in priority segments and markets.
Website conversion rates increase through structured optimisation.
Marketing and Sales trust the data and use it actively.
The MarTech team operates as a strategic performance enablement function, not a support desk.
Leadership has clear visibility into marketing’s contribution to pipeline and revenue.
The team you’ll be a part of
Working closely with Marketing, Sales and Commercial leadership, you translate complex performance data into clear direction, informed trade-offs and continuous improvement.
You are accountable for the quality, reliability and usability of marketing performance data, with execution delivered through your team and partners.
You lead and develop a small, high-impact MarTech team responsible for:
Website experience & conversion optimisation
CRM, automation & lifecycle enablement
Marketing data, tracking & performance insights
Together, the team ensures that our website, marketing systems and data foundation are reliable, well-governed and continuously optimised.
Your leadership creates clarity on ownership, standards and priorities, enabling the team to focus effort where it creates measurable commercial impact, rather than reactive execution.
Desired experience and competencies
What does it take to work for LanguageWire?
What you’ll need to bring
5+ years in B2B marketing operations, MarTech, growth or performance roles.
Proven experience owning paid performance with:
Google Ads (Search) and LinkedIn Ads,
